[PATCH v2 0/1] feat: add support for hyper-v virtual machine

['Gourav Singh' via isar-users]

Changes in v2:

- Rename machine from hyper-v to hyper-v-amd64 to reflect target arch
- Fix commit message: .wic is an intermediate artifact, not a co-equal output
- Add SPDX license header to kas yaml
- Update copyright from ilbers GmbH to Siemens AG in all new files
- Trim RECIPE-API-CHANGELOG.md entry to remove verbose build instructions

[PATCH v2 1/1] feat: add support for hyper-v virtual machine

['Gourav Singh' via isar-users]

Introduce a new `hyper-v` machine targeting Microsoft Hyper-V virtual
machines on amd64. The machine uses WIC with an EFI partition layout,
GRUB as the bootloader, and produces a `.vhdx` disk image via the ova
image type, which depends on wic as an intermediate build artifact.

Add Kconfig entry, kas machine yaml, machine config, and multiconfig
files for bullseye, bookworm, and trixie. Register the new multiconfigs
in mc.conf and document the addition in RECIPE-API-CHANGELOG.md.
